Get information about supported cipher suites. Use the function iteratively to get information about all supported cipher suites. Call with idx=0 to get information about first cipher suite, then idx=1 and so on until the function returns NULL. @strong{Returns:} the name of @code{idx} cipher suite, and set the information about the cipher suite in the output variables. If @code{idx} is out of bounds, @code{NULL} is returned. @end deftypefun
